STAGE-SCREW.

Specification of- IlettrsPatent-.-

Application filed July 25,1912. Serial No. 711,598.

To all whom it may concern:

Be it known that I, HARRY FOSTER LEEs, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented new and useful Improvements in Stage-Screws, ofwhich the following is a specification.

My invention relates to an improved form of stage screw adapted foremployment with stage scenery braces as customarily used,

misplaced; second, the convenient provision made for replacing of thescrews when they become worn or damaged, and finally 1ts adaptation touse as an ordinary portable stage screw when desirable for specialsituations, etc. My invention is thus equally suited for dual use as apermanent and fixed part of scenery brace and as a separable hand screwof the ordinary type butwith the additional. feature of a detachablescrew.

These and other features of myimproved device are shown in theaccompanying drawing in which the reference characters of thedescription are applied to like parts in the diiferent views.

In the drawing Figure 1 illustrates in perspective the lower portion ofa scenery brace having the device of my invention employed therewith andFig. 2 is a sectional elevation ofmy improved hand screw.

In the figures 1 indicates the lower end of the usualstage scenery bracehaving secured to it the curved foot-iron 2 having a plurality ofapertures 3 therein to receive the securing screw, this being of theordinary type in common use. Fit-ted to one of the apertures 3 is shownthe hand-screw of my invention comprising the lower screw portion 5having integrally formed therewith a flat collar flange 6 and anupwardly extending squared shank 8. The shank 8, as shown, passesupwardlythrough an aperture 3 of the foot iron and the screwhandle-portion 10 is fitted thereon, so that they will turn together, byhaving its central collar portion 11 provided with a squared recess 12snugly fitting the squared shank 8. In this position, as shown, the footiron is arranged between the screw flange 6 and a correspondingfiange 14on the central por- Patented Mar. 4, 1913.1

tion' 11 of the handle and in this position,

it is permanently clamped by meansof a suitable set screw 15 carried inthe portion 11 to be screwed home into small notches 16 formed in thesquared screw shank 8. The

set screw 15 is desirably countersunk and round-headed so as not tointerfere in the manipulation of the handle. In consequence of thisarrangement it will be seen that my improved hand screw is permanentlyclamped on the foot iron 2, of simple construction and as ordinarilyused, thus converting it into a complete attaching device in a mosteconomical manner. F urthermore the. replacing of the screws 5 and theattachment of the hand-screw as a whole to the foot-iron is accomplishedin a single operation or as aforesaid my improved hand screw may be usedin the ordinary manner with the lower clamping flange 6resting on thefoot iron. I

I am aware'that certain forms of stagescrews permanently secured to thefoot-irons have been suggested, but those with which I am acquaint-edwere single-piece screws, so that when worn or broken the whole screwhas to be thrown away, and thisis one of the disadvantages that I haveovercome.

Having described my invention, I claim,

1. A stage screw comprising a screw ele-- ment, an upwardly extendingsquared shank integral with the screw element, a handle element having arecessed collar fitted to the shank to secure them to turn together anda set-screw in the collar to engage the shank for the permanentattachment of the screw and handle elements.

2. A stage screw comprising a screw element, a clamping portion on saidscrew element, an upwardly extending shank on the screw-element, ahandle element, a cooperating clamping portion on the handle element,

said handle-element being recessed to reshank on one of the elements,and engaging means on the other elementto engage said shank to couplethe parts together.

4;. A stage screw device for a scenerybrace having a foot-iron attachedthereto, comprising a screw-elernent, a shank on the screw-element toupwardly extend through the foot-iron, a clamping surface on saidscrew-element to engage the under surface of the foot iron, a handleelement to engage with the foot-iron upper surface, said handle elementbeing recessed to receive the screw-shank and means to secure the handieand screw elements in a fixed relation.

5. A stage screw device for a scenerybrace having a foot iron attachedthereto, comprising a screw-element, a squared shank on thescrew-element to upwardly extend through the foot-iron, a clampingcollar on the screw-element to engage the under surface of the footiron, a handleele1nent, a cooperating clamping collar on thehandleelement to engage the foot-iron upper surface, said handle-elementhaving a squared recess fitted to the screw-shank thereby to turntogether and a set screw carried by the handle-element to engage theshank and secure the parts.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
